Pupillary dynamics in diabetic and nondiabetic patients following uneventful phacoemulsification.
Clin Exp Optom
January 2025
Department of Ophthalmology, Gaziantep City Hospital, Gaziantep, Turkey.
Clinical Relevance: Although laser refractive surgeries and multifocal intraocular lens implantation are generally avoided in patients with diabetic retinopathy, a substantial proportion of well-glycaemic-controlled type 2 diabetes mellitus patients are considered for these procedures. Pupil dynamics play a significant role in determining postoperative satisfaction in these patients.
Background: To evaluate pupillary dynamics in patients with and without diabetes following uneventful phacoemulsification surgery.
Clinical Characteristics and In Vivo Confocal Microscopic Study in Candida Keratitis.
Transl Vis Sci Technol
January 2025
Beijing Institute of Ophthalmology, Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University, Beijing, China.
Purpose: To clarify the clinical and imaging characteristics of Candida keratitis using in vivo confocal microscopy (IVCM) for improved early diagnosis and management.
Methods: A retrospective study of 40 patients with Candida keratitis at Beijing Tongren Hospital from January 2015 to December 2023 was conducted. Data included demographics, risk factors, clinical assessments, lab tests, and IVCM images.
Purpose: The light adjustable lens (LAL) (RxSight, Aliso Viejo, CA) is a premium intraocular lens that allows for correction of residual refractive error and astigmatism following implantation. Herein, we describe the surgical approach and evaluate the visual outcomes of patients following scleral fixation of the LAL.
Methods: Retrospective, single-surgeon surgical case series of 3 patients (3 eyes) with intraocular lens complications, who underwent combined pars plana vitrectomy and sutureless needle assisted intrascleral haptic fixation of the LAL between April 2022, to August 2023.
Manual versus Markerless (Image-guided System) Toric Intraocular Lens Implantation Outcomes for Astigmatic Correction in Cataract Surgeries.
Acta Med Philipp
December 2024
Department of Ophthalmology and Visual Sciences, Philippine General Hospital, University of the Philippines Manila, Manila, Philippines.
Objective: Toric intraocular lens implantation has been used to correct corneal astigmatism during cataract surgery. The study aimed to compare the visual outcomes between manual vs markerless toric intraocular lens implantation in astigmatic correction.
Methods: The medical records of patients at American Eye Center who underwent phacoemulsification by multiple surgeons with insertion of monofocal or multifocal toric lenses via manual marking and markerless method from 2010-2019 were reviewed.

An intraocular lens (IOL) replaces the natural crystalline lens during cataract surgery, and although the vast majority of implants have simple optics, "advanced technology" IOLs have multifocal and extended depth of focus (EDOF) properties. Optical concepts are evaluated here, with image contrast, focal range, and unwanted visual phenomena being the primary concerns. Visual phenomena with earlier bifocal diffractive lenses led to alternative diffractive designs (trifocals, etc.
